BOSTON (CBS) – A man in his 20’s from Worcester County is the second person in Massachusetts to be diagnosed with the U.K. COVID-19 variant, the Department of Public Health confirmed Wednesday.

The U.K. variant, also known as B.1.1.7., spreads faster than other variants. It is thought to be up to 70 percent more transmissible than the original strain, but the CDC says there’s no evidence it’s more deadly.
